It is interesting how many highways actually travel through interchanges on ramps while the fast lane goes in the opposite direction. One example would be I-40 and Sam Cooper Blvd in Memphis, I-79 west junction with I-70, and I-40/65 west in Nashville.
I would suggest I-75 in Detroit just as it hits I-375. Drops to 30MPH as it leaves the mainline by "exiting" to the right. However, the straight part to the 375 is labeled as the exit.
I-95 in Massachusetts- perhaps twice.
CA 23 north on the Moor Park Freeway leaves the limited access grade which becomes CA 118 east on the Ronald Reagan Freeway:

I-94 from I-694 in Maple Grove, MN
I-90 at I-94 in Billings and westbound at Tomah
I believe we've had this discussion before, perhaps multiple times, but I can't seem to find it.
There is an acronym for these that to my knowledge is only used among the roadgeek community: TOTSO (Turn Off To Stay On).
I-90 does it twice in a row near Cleveland: https://www.google.com/maps/@41.6007969,-81.4691644,14.21z/data=!5m1!1e1
No loop ramps, but I-90 is pretty clearly the "turning" movement in both cases.

That's only a single highway exiting itself, while the others are "bumps" where 2 highways do it at once.
I guess that's why you're still holding the mic.
Also, I-70 in Breezwood.
I-5 northbound does this twice due to it taking over old portions of US routings: at US-101 in downtown Los Angeles, and at CA-99 at Wheeler Ridge.
(although you could argue that those have both become effectively left-hand exits)
I-73 does it twice around Greensboro, and with a damn loop ramp on the south side going northbound. And on the west side of town, it has an I-73 exit number to STAY on I-73... (I-840 should be considered a "left exit" here instead.)
I-70 on the east side of Topeka, KS as it exits the Turnpike - which, by the way, I actually drove yesterday.

You do know there's a command, right?
I'm surprised that no one has yet mentioned exit 24 of the New York Thruway in Albany. There, the mainline of the Thruway changes designation from I-87 to I-90 and you have to get off at exit 24 to stay on the same interstate.

YES.
I wonder why nobody has thought about just realigning 90 onto the Thruway, then having it take over the whole of the Berkshire Connector?

It got mentioned in the previous thread (https://www.aaroads.com/forum/index.php?topic=16421.0) on the subject.
Maryland has a few of these, depending on how the OP has defined things:
- MD 140 exits itself at the northern terminus of I-795 west of Reisterstown.
- I-95 exits its Capital Beltway incarnation in College Park.
- US 301 exits itself in Bowie.
- US 391 also exits itself north of Waldorf.
- US 50 exits itself in Queenstown.
- MD 24 exits itself in Bel Air.
Since other Interstate Bumps have been mentioned...
Both I-64 (from the west) and I-70 (from the east) bump each other and exit I-55 in East St Louis, as I-55 is continuous thru the bump

I-5 in Rigde Route exits itself In a similar fashion when it is at the CA-99 interchange.Also I-80 exits itself when it at the I-305/US-50 interchange in West Sacramento, CA.
Westbound I-96 might exit itself at exit 37, as I-196 continues straight ahead while I-96 veers off to the right.
Eastbound I-96 might exit itself at exit 31A, as unsigned I-296 continues straight ahead while I-96 veers off to the left. (Also, WB I-96 briefly drops to one through lane in this vicinity)
I-83 does it twice within 5 miles: at exit 41A (https://www.google.com/maps/@40.2385908,-76.8928715,17z?hl=en), and at exits 46A-B (https://www.google.com/maps/@40.2542498,-76.8133658,17z?hl=en).
I also think I-81 north at I-78 might count, considering the 2 lanes approaching the interchange continue onto I-78, while 2 new lanes form on the left for I-81's continuation.

Probably because the designers thought I-90 should have a non-toll section in NY.
Northbound I-5, San Diego Freeway exits itself at I-5/I-405 onto I-405.
I-280 north at CA-1 north (19th Avenue) San Francisco

I-10 in Downtown Los Angeles, twice. The through movements go to CA-60 (eastbound) or San Bernardino Freeway/US-101 (westbound)
VA-286 (Fairfax County Parkway) exits off itself eastbound at VA-289 (Franconia-Springfield Parkway).
DE-1 Northbound at US-13 in Bear.
I-264 eastbound at Waterside Drive, largely due to the interchange predating the interstate, IIRC.
US-13 SB at the start the Suffolk Southern Bypass, with the through route (US-58) no longer a freeway.
I-96 and M-5 at the I-275/I-696/M-5 interchange.

Since the fastest route is the free road, shouldn't that stay I-90? I'm not sure it needed to be built but since it was, one would think it deserves the I-90 designation.

Yes, but it's because of the design of the interchange. It could have easily been designed a bit differently to make I-86 the through route. That's not the case with most other examples, where the route clearly exits onto a different road.

The I-86 sign has up arrows, it takes a flyover, it uses the right lane, it's marked on signs farther back as "I-86, next right"...I don't know what else you want. It exits itself.

It does feel somewhat odd when highways switch which lanes they take. If I-99 were extended to Rochester, it would start on the slow lane then move into the fast lane.

It goes from Southern Tier Expressway to... Southern Tier Expressway. It's the same road on both sides of the interchange, it just

All of the other examples that exit themselves keep the same name. For the I-80 / I-76 example, they are both I-80 and I-76 on their respective facilities even after exiting. For the Fairfax County Parkway example, it continues as such even after exiting.
Several in the Indianapolis area due to the general lack of State highways inside I-465 (presently only I-65 and I-70) and included are only the ones where the exit ramp is at something akin to full speed and where no traffic lights are present at the junction:
- SR-37 is part of I-69's Exit 0 onto I-465 south on the northeast side of town while Binford Blvd is the through road
- US-31 exits onto I-465 east on the southside of town with East Street being the continuation
- I-74 technically exits itself onto I-465 west on the eastside with Southeastern Ave continuing but the construction project a while back indicates Southeastern Ave now as Exit 94. The ramp speed on I-74 is less than proceeding on Southeastern Ave, however.
I-55 NB in Memphis really bad you have to take a cloverleaf ramp to stay on I-55. Also I-75 NB in Lexington you have to exit to stay on 75 the mainline continues as I-64.
I 15 in montana despite being the interstate with the mileage and exit numbers when it's duplexed with I 90 exts onto itself. drops down to one lane too. same thing with the I 90 west western terminus with I 94 in montana.

VA-286 (Fairfax County Parkway) exits off itself eastbound at VA-289 (Franconia-Springfield Parkway).
....
I'd say this is even more of an exit off itself going the other way because in that direction you have to exit to the right and go around a loop ramp, whereas eastbound the right lane goes right, the left lane goes left, and the middle lane splits.

I-5 northbound does this twice due to it taking over old portions of US routings: at US-101 in downtown Los Angeles, and at CA-99 at Wheeler Ridge.
(although you could argue that those have both become effectively left-hand exits)
Actually, it does it a third time at the I-580 exit; the 2+2 configuration grows an extra right lane, and that lane plus the split original right lane turns to the right as the continuation of I-5. That's the last instance of a TOTSO on NB I-5 in CA; the next one's up in Portland at the I-405 split.

I-90 exits the Berkshire Extension to go through Albany.

I-5 at I-580
I-10 in Downtown Los Angeles, twice. The through movements go to CA-60 (eastbound) or San Bernardino Freeway/US-101 (westbound)
The through route eastbound for the 10 in Downtown LA is the 5/10 Golden State Fwy merge, with the 5 south and 60 east exiting to the right. The 10 then exits a mile thereafter to the right onto the San Bernardino Fwy and the 5 north is the through route.
US 10 comes into the Appleton, WI area from the west as a freeway. At I-41, the freeway picks up the WI 441 designation. Several interchanges later, on Appleton's south side, US 10 hops off of the freeway at Oneida St, and continues on eastward towards Manitowoc, WI as a mostly two lane surface highway.
Also in Wisconsin, as it progresses eastward, WI 29 picks up WI 32 as it nears the Green Bay area. As the combined WI 29/32 highway nears I-41 as a freeway, WI 29 hops off of the freeway at its last crossroad interchange (Packerland Dr) to continue on into the city as a surface street (Shawano Ave), while the freeway continues on for one more interchange as WI 32 to end at I-41.

There used to not be an exit for I-90 from the express lanes. It must have been added the last time they redid the Dan Ryan.
Technically it is a Slip Ramp from the Express to the Local that becomes the Left-most Exit Only lane for the Locals Left Exit, but it is signed as an exit to the Skyway from the Express lanes
On the southwest side of downtown San Antonio, I-10 exits itself to merge onto I-35 north to be cosigned, where US 90 takes over the mainlanes. It has it's own exit number and everything.

Here's a highway where different routes from both sides exit themselves. NB IN 25 exits from the west and NB US 35/WB US 24 exit from the east.
Which also begs the question: What route is the small section in between the two exits?
The Hoosier Heartland Highway.
It would be an interesting question to ask INDOT though.

CA 23 north on the Moor Park Freeway leaves the limited access grade which becomes CA 118 east on the Ronald Reagan Freeway:
(https://live.staticflickr.com/65535/47954159036_7a0841d44f_4k.jpg) (https://flic.kr/p/2g4xAMs)IMG_1340 (https://flic.kr/p/2g4xAMs) by Max Rockatansky (https://www.flickr.com/photos/151828809@N08/), on Flickr
Not only does CA 23 north exit the freeway (which becomes CA 118 east), but going the other way, CA 118 west exits the freeway (which becomes CA 23 south). If you stay on the freeway, the exit numbers seem a little odd. NB->EB : 17, 19, 20, 19A, 19B; WB->SB: 19B, 19A, 18, 19, 17.
You can see in Max's picture that the CA 23 ramp is Exit 20A, and the freeway continuation as CA 118 is Exit 20B. The corresponding BGS the other direction hasn't been updated with exit tabs, though the gore point sign identifies the CA 118 ramp as Exit 18B.
Also, I-210 in Pasadena at the CA 134 (and 710 stub) interchange.

It is interesting how many highways actually travel through interchanges on ramps while the fast lane goes in the opposite direction. One example would be I-40 and Sam Cooper Blvd in Memphis, I-79 west junction with I-70, and I-40/65 west in Nashville.
First, Sam Cooper was going to be the route for I-40 until the community activists stopped the through freeway.
Second, In spite to turning off to stay on. Keeping the farthest left lanes being the through route of an interstate is not necessarily the most economical or even the best for traffic flow.
When they redid the I-20EB / I-635NB intersection they deleted the simple right on I-20. Now you keep left to turn right. Probably half of the time I come through that intersection, I stay right and wind up on I-635. I might add that as much or more of the traffic coming into that intersection keeps travelling North as that which veers east on I-20.
Thirdly, I-55 on the other side of town is FAR worse.
I-49 in the Joplin, MO area. Especially notable northbound. Faster to leave the Interstate to rejoin it later using MO-249. Sure would be nice for them to fix the Carthage interchange and just move I-49 to it.

Many more I am sure. Many mentioned, but to point out it is very common.

I would suspect that officially it is either SR 25 or US 24. Although INDOT does have the audacity of removing designations from highways, so maybe they gave it over to "Local Control".

Maryland has a few of these, depending on how the OP has defined things:
- MD 140 exits itself at the northern terminus of I-795 west of Reisterstown.
- I-95 exits its Capital Beltway incarnation in College Park.
- US 301 exits itself in Bowie.
- US 391 also exits itself north of Waldorf.
- US 50 exits itself in Queenstown.
- MD 24 exits itself in Bel Air.
One that I hadn't noticed until today, I-695 outer loop at I-97.
Another one for I-695 is inner loop at MD 702

In Michigan, it would be a connector with an internal MDOT designation (e.g. Connector 24) but no actual route number assigned.
I actually have a simple criterion for which highway is the dominant one: the left-lane rule.
Simply put, if the left lane of any highway (discounting exit lanes) goes to a different highway number than the highway that was signed before, the highway exits itself and leaves a more dominant highway. However, if the left lane of the second highway in the opposite direction enters the other highway, both highways are dominant.
An example of a clearly-dominant interchange would be Exit 304 on I-80 in Pennsylvania. A codominant interchange would be that of PA 33 and US 209 a few miles southbound of Exit 304. A recessive interchange would be Exit 47A on I-80 in New Jersey, where I-80 exits from itself, and the left lane goes onto 280.
what about the i-80/76 split near big springs, NE.. this seems like it sort of qualfies..

Technically it is a Slip Ramp from the Express to the Local that becomes the Left-most Exit Only lane for the Locals Left Exit, but it is signed as an exit to the Skyway from the Express lanes
before that you need to go all the way over the slip point not as close. and the other side did not have an direct link to express
I kept thinking of more examples in Indiana so I deleted my previous posts and am consolidating here.
US 24/35 and IN 25 both exit off the Hoosier Heartland highway just southwest of Logansport.
US 20 and IN 2 exit themselves at an interchange in Rolling Prairie
IN 933 exits itself off Eddy St in South Bend (also ending a wrong-way concurrency)
US 41 exits itself twice, once at each end of IN 63 north of Terre Haute, and once at an interchange at Vincennes, where US 50 exits itself once and US 150 exits itself twice within a mile.
Before I-530 was born, US 65 was THE highway connecting Little Rock and Pine Bluff, AR. It was an interstate-grade (for the 60s when built) road until you got to Pine Bluff, where you were welcomed into town with big warning signs: WARNING: 8 TRAFFIC LIGHTS NEXT 6 MILES. Those 6 miles were known as The Martha Mitchell Expressway.
In the mid 90s, AR started building the Pine Bluff bypass that would become the final 11 miles of I-530. The first step was to build a new exit to keep US 65 southbound as a through-route while the bypass was being built. (north bound stayed on its original route during this time) This new exit was designated as an exit for the continuing US 65 at the time (an all-traffic exit, yes...but it still has BGSs with US 65 and "Pine Bluff" as the lone destination). When the bypass opened, the US 65 shield was changed to US 65B.
https://maps.app.goo.gl/eoso9FUTpWLAYJdEA
Of course, since AR refuses to sign concurrencies, the I-530 BGS lists all US 65 destinations.
During the last 11 miles, US 79 & US 63 merge with I-530/US 65. So at the end of I-530, the last exit has US 79 & US 63 exiting the main lanes and continuing up the Martha Mitchell Expressway north bound briefly until they both turn off by the Pine Bluff mall.

US 59 south of Nacogdoches, TX exits to a surface street version of itself at a diamond interchange.

I-275 in Ohio exits itself onto I-74 west in a trumpet interchange. You take the exit on the right to go onto the I-275 north-I-74 and US 52 east concurrency.
I-85 exits itself on both sides of downtown Atlanta (the Downtown Connector) going northbound AND southbound...
Surprised nobody has mentioned the 101 in both directions at the 134 and 170 interchange (aka the Hollywood Split). Or EB 580 at EB 205
US-35 exits from OH-735 to cross the Silver Memorial Bridge in Gallipolis, OH. OH-735 was originally US-35 until the Silver Bridge collapse at which point the new bridge was built to enter WV on the south side of the Kanawha, thus requiring a new approach from the Ohio side.

I don't think I would count this. If you go by the left lane rule stated earlier it wouldn't count. If you are in the left lane on US 35 eastbound you do not have to make any lane changes to continue in the left lane of US 35. OH 735 is just a left exit off of the highway.

A-10 exits itself once in Montréal, and it also did so in Sherbrooke before some engineer decided to change the easternmost segment to A-610.
A-15 does this three times: in Longueuil to join Pont Champlain, then twice at A-40 in Montréal.
A-20 also does it three times: at Échangeur Turcot, then at the same spot as A-15's self-exit, then at A-25.
A-40 does it five times: twice in Trois-Rivières and thrice in Québec City.
A-55 does this three times: near Magog as it joins A-10, in Drummondville as it joins A-20, and in Saint-Léonard-d'Aston as it leaves A-20.
A-73 exits itself two times, both in Québec City.
I feel like I-290/IL exits itself at the I-355 interchange in Itasca.
It is a standard Freeway Y interchange, but the "Thru" movement is 290 East -> 355 South and 355 North -> 290 West. 290 Exits/Enters the "mainline" to/from the right utilizing 2 lanes, while the Thru 290 <-> Thru 355 movements utilize the 3 left lanes
